LIQUID DISTRIBUTING OR DOSING TANK AND MECHANISM.

SPECIFICATION forming part of Letters Patent No. 759,233, dated September 16 v1902. Application filed January 6, 1902. Serial No. 88,514. (No model.)

'10 all whom it may concern: I

Be it known that-I, SIDNEY W. MILLER, of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements in Liquid Distributing or Dosing Tanks and Mechanism; and I do hereby declare that the 'followingis a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters'of reference marked thereon,

which form a part of this specification.

This invention relates to an apparatus designed for intermittingly controlling the flow of liquidfrom a central tank or receptacle to a plurality of tanks or receptacles and so arranged that said plurality of receptacles may be filled or charged in predetermined rotative order from said main tank or receptacle.

The invention has been designed more especially for use in connectionwith a system for the septic treatment of sewage for puritying the same, said apparatus being adapted to be located between the septic tank and the contact orfilter beds, so as to receive the sewage from the septic tank and properly distribute the same to said contact or filter beds. I

The invention consistsin the matters hereinafter set forth, and more particularly pointed out in the appended claims.

Inthe drawings, Figure l isa plan view of an apparatus embodying my invention. Fig. 2 is a transverse vertical section on line 2 2 of Fig. 1. Fig. 3 is a horizontal section taken on the indirect line 3 3 of Fig. 2. Fig. 4 is a view, partially in longitudinal section and partially in rear elevation, of the apparatus shown in Fig. 1.

Fig. 5 is a vertical section of an apparatus, showing my invention applied to another form of siphon.

As shown in the drawings, A designates a tank which maybe called a main distributing or dosing tank andis adapted for connection Witha source supplying liquid, as a septic tank, through the medium of a pipe A. Said tank is made of masonry or other suit able construction and when used in connection with a sewage-purifying system is made of sufficient capacity to contain a desired charge or dose of sewage to be discharged upon the several contact or filter beds connected therewith. The contents of said tank are adapted to be emptied into a plurality of receptacles. as the contact or filter beds referred to, through themedium of a plurality of siphons B, which are shown as located near one side wall of the tank. The short leg b of each of said siphons consists of a down wardly-opening bell, which is supported on the upper end of the longer leg 1) thereof in the manner shown in Fig. 2 orother suitable manner, and said longer leg of each siphon communicates with a trap b having an upturned portion which empties into a pipeor conduit 0, leading to one of the contact or filter beds or other suitable place for the disposal of liquid discharged from said tank. Located in said tank in rear of the siphons is a series of deep chambers or wells D, equal in number to that of the siphons, and said chambers are severally associated with said siphons. Said chambers D are opened at their upper ends and closed at their lower ends. Said chambers and their associated siphons are designated on the draw ings and will be hereinafter referred to as No. 1, N0. 2, No. 3, and N0. 4, respectively.

her or well D is a downwardly-opening bellshaped receptacle D', shown as supported on short legs (1, which rest on the bottom of said chamber, but may be otherwise supported. Said bells are made of less diameter than the chambers, as clearly shown in Fig. 1. Each siphon comm unicates with its associated chamber through the medium of a pipe E, which enters the top of said siphon and dips at its other end into said chamber. Said pipes E constitute drain-pipes for the chambers,

Contained within each cham-,

each chamber being emptied through said at all times in the operation of the apparatus.

Each of said bells D of the chambers or wells D communicates through the medium of a three of the chambers starting-pipe D with asiphon associated with another chamber D of the series. As herein shown, each pipe D enters one of said siphons below the seal-level in the trap thereof,though it may enter said siphon above said seal-level. Eachof said pipes D passes upwardly th rough the open top of the well or chamber D and thence laterally and downwardly toward the siphon with-whichit communicates.

As herein shown, the drain-pipe E of each siphon communicates with the chamber D next adjacent thereto, the pipe E of siphon No. 1 communicating with No. 1 chamber D. the pipe E of siphon No. 2 communicating with No.2 chamber D, and so on throughout the series, while the starting-pipe associated with chamber No. l communicates with siphon No. 2, the starting-pipe associated with chamberNo. 2communicates with siphon No. 3, and so on. This arrangement. whilea preferable one, may be variedthatis to say, the siphon associated with each chamber and through which said chamber is emptied need not necessarily be the siphon next adjacent to such cha'mber,'it only being necessary that the siphon associated with one chamber of the series in a manner to empty said chamber shall communicate with a starting-pipe which is connected with a bell in a chamber associ- 'ated with another siphon of the series. The term associated siphon hereinafter employed in connection with the chambers is understood to mean the siphon which empties the chamber referred to. In the present instance the siphonsand chambers are arranged in straight lines, so that the starting-pipe of the chamber No. 4 which communicates with siphon No. 1 must pass from one end of the series to the other. The siphons and associated chambers may be arranged in circular series, in which eventthe starting-pipes will all be of practically the samelength. In the usual working condition of the apparatus Dare filled with liquid The traps of all the siphons are also filled, as well as the extension-chambers' D Ifit be assumed, for instance, that chambers No. 1, No. 2, and No.3 be filledand chamber No. 4 be empty, the operation of the apparatus is as follows: The water entering through the pipes A fills the tank A to or above the level of the tops of the chambers D. The traps at the discharge ends of the siphons are so "proportioned with respect to the tank that the maximum liquid-head in said tank is not'sufiicient in itselfto start said siphonsinto operation. A has been filled to the level of the tops of said chambers D. a further supply of liquid to the tank overtlows into the empty chamber No. 4 and fills or partially fills the same. The filling of said No. 4 chamber D causes the liquid to rise around the bell D in said chamber, and the liquid enters the lower end of the bell and to an extent displaces theair therein, causing said air to be transferred through the pipe D to the trap of siphon and one is em pty.

When said tank 7 No. 1. As the level of the liquid rises in No. 4 chamber Dthepressure in the pipe D is increased and transmitted to siphon N0. 1 until said pressure is sufficient to overcome the seal in the trap of said No. 1 siphon and start said siphon into operation. Said siphon No. 1 continues in operation until the chamber A is emptied of its contents and said contents transferred to the tank or receptacle with which the pipe 0 communicating with said siphon empties. At the time siphonic operation begins in said siphon No. 1 a suction is produced in said siphon which acts to draw through the drain from the chamber D associated with siphon No. 1, said chamber being emptied to or below the lower end of the bell therein. After said tank has been emptied through siphon No. 1 in the-manner described and chamber D No. 1 associated withsaid siphon emptied (chambers D No. 2, No.3, and No. 4 being at this time practically filled) said chamber No. 1 will remain empty until the-tank Ais again filled to the level of the top of said chambers. Thereafter liquid enters said chamber No.- 1 and through the bell D and pipe D exerts pressure on siphon N0. 2 in the manner hereinhefore described and starts said siphon No. 2 intooperation to empty said tank A and the chamber D associated therewith. The several siphons of the series are thus brought successively into action until all of the siphons have been operated and successive charges or fdoses of the liquid discharged therethrough into the several tanks orreceptacles communicating with thepipes C, after which such operations will be repeated in the same order so long as liquid is supplied to the tank A.

The lower ends of the pipes D at their entrance to the siphon-trap are formed to provide traps in said pipes to prevent the escape of air from said siphons through the chambers D at times when said chambers are not filled. As herein shown, said lower portions of the pipes D are inclined downwardly and outwardly from said traps to the vertical parts of the pipes, thereby constituting traps in said pipes between said vertical parts of the pipes and said siphon-traps. Any other familiar form of trap may be employed for this purpose, as found most convenient or desirable. When the level of the liquid has been depressed in the siphon-traps below the level of the entrance of the parts D thereinto, the pressure in the siphons acts to drive the liquid in said inclined parts of the pipes backwardly into the vertical part-s thereof, and said lower or trap ends of the pipes are made of such length that when the Water is driven therefrom into the vertical parts of the pipes it will produce a column which will more than counterbalance the pressure in the siphon due to the liquid-head in the tank A. When the chamber D associated with the pipe D which communicates with the siphon next to be broughtinto operation is filled,

-pipe E the liquid sirably provided with vent-pipes D which communicate with the pipes above the bells and extend downwardly and terminate above the upper ends of the bells. Said pipes are provided to insure that the bells andpipes be.

thoroughlyventilated after each operation of the siphons associated therewith. The lower ends of the said pipes determine the sealinglevels of the several bells.

In Fig- 5 I have shown my invention applied to a double-trap siphon. As shown-in said figure, the trap 17 of each siphon is provided with an auxiliary or blow-off trap B, having a less depth of seal than the main trap of said siphon. Said trap consists of a smallpipe, which is shown as located outside of the main trap 19 thoughit may be located within said maintrap. One end of said pipe enters the descending part of the trap above.

the bend thereof and preferably, though not necessarily, below the seal-level ther.ein, and the other end of the-lpipe enters the outlet or ascending end of the trap, preferably above said seal-level. The starting-pipe D associated with .each siphon enters said :blOW-Off trap, though, if desired, said starting-pipe.

may enter directly into the main trapof-the siphon. The operation of the apparatus when connected with this form of siphonis the same as that hereinbefore described exceptthat the air-pressure in the startin g-pipe forces the seal of the blow-01f trap, (it having a less depth of seal than 'the main .trap,)

which releases the air. in themain trap and starts the siphon into action. An advantage of connecting thestarting-pipe withthe-blowoff trap is that inasmuch as there is a less quantity of water to. be displaced toforce the seal the chambers and bells D D, respectively, may be made smaller than in the firstmentioned construction.

It is obvious that the invention may be otherwise applied and that the structural details of the apparatus shown may be varied without departing from. the spirit of my invention, and I do not Wish to be limited to such details except as hereinafter made the subject of specific claims. For instance, the chambers D need'not necessarily be located in the tank A, it only being "necessary that they communicate with the tank or its sourc e of liquid-supply, so as to be filled when said tank is filled to the required level. over, the relation of the chambersD communicating with the chambers I), may be varied so long" as the proper communication between the same and said chambers is main tained, so that said chambers are emptied through said drain-pipes.
